A Correct answer
Explanation

The upper two chambers of the heart are called atria (singular: atrium). The right atrium receives deoxygenated blood from the body, and the left atrium receives oxygenated blood from the lungs. Ventricles are the LOWER chambers, and 'Coronus' is not an anatomical term related to the heart.
